Materials. The following materials are required to rig this load:
Sling set (25,000-pound capacity) with one additional apex fitting.
─ Additional chain length, part number 38850-00053-102, from a 25,000-pound capacity
sling set (2 each).
─ Additional coupling link, part number 9779135, from a 25,000-pound capacity sling
set (2 each).
OR
Sling set (40,000-pound capacity) with one additional apex fitting.
Tape, adhesive, pressure-sensitive, 2-inch wide roll.
Cord, nylon, Type III, 550-pound breaking strength.
Webbing, cotton, 1/4-inch, 80-pound breaking strength.
z
Personnel. Two persons can prepare and rig this load in 15 minutes.
z
Procedures. The following procedures apply to this load:
Preparation. Prepare the load using the following steps:
─ Extend the front lift provisions and lock in place using the attached pin and safety pin.
─ Roll up the windows in the cab.
─ Tape all windows, lights, and reflectors.
─ Remove the air intake cowling by loosening the clamp and twisting off. Place the
cowling on the floor board of the passenger's side.
─ Ensure the front wheels are pointed straight ahead. Tie down the steering wheel using
the driver's side seat belt.
─ Fold the side view mirrors back and secure with tape or Type III nylon cord.
─ Stow the mud flaps by bending and hooking on the mud flap hooks.
─ Engage the vehicle parking brake and put the transmission in neutral.
─ Ensure the fuel tank is not over 3/4 full. Inspect fuel tank cap, oil filler cap, and
battery caps for proper installation.
─ Tape the filler pipes behind the cab on the driver's side to prevent the sling legs from
becoming entangled.

Hookup. The hookup team stands on the rear of the vehicle. The static wand person
discharges the static electricity with the static wand. The forward hookup person places apex
fitting 1 onto the forward cargo hook. The aft hookup person places apex fitting 2 onto the aft
cargo hook. The hookup team then carefully dismounts the vehicle and remains close to the
load as the helicopter removes slack from the sling legs. When successful hookup is assured,
the hookup team quickly exits the area underneath the helicopter to the designated rendezvous
point.
Derigging. Derigging is the reverse of the preparation and rigging procedures.
RIGGING STEPS
1. Connect 2 sling legs to apex fitting number 1. Attach one extra chain length to each existing
chain on each sling leg using one coupling link (for 25,000-pound capacity sling sets only).
Position the apex fitting on the forward end of the bed.
2. Loop the chain end of the sling legs through their respective lift provisions located behind the
vehicle cab. Place the correct link from Table 2-44 in the grab hook and secure all excess
chain with tape or Type III nylon cord.
3. Cluster and tie or tape (breakaway technique) the sling legs on top of the spare tire to
prevent entanglement during hookup and lift-off.

Certified Dual-Point Rigging Procedures for Trailers
INTRODUCTION
3-1. This chapter contains rigging procedures for dual-point trailer loads that have been certified for sling
load. Each rigging procedure is found in a paragraph that includes a description of the load, materials
required for rigging, and steps to complete the procedure. An applicability paragraph is also a part of each
paragraph and identifies the certified loads. The certified dual-point rigging procedures for trailers are in
this section. Paragraphs 3-2 through 3-25 give detailed instructions for rigging loads.
Note. Reach Pendants may be used on dual-point loads. Place a reach pendant on each apex
fitting. A static discharge person is not required when using a Reach Pendant.

Materials. The following materials are required to rig this load:
Sling set (40,000-pound capacity) with one additional apex fitting.
Tape, adhesive, pressure-sensitive, 2-inch wide roll.
Cord, nylon, Type III, 550-pound breaking strength.
Webbing, cotton, 1/4-inch, 80-pound breaking strength.
z
Personnel. Two persons can prepare and rig this load in 30 minutes.
z
Procedures. The following procedures apply to this load:
Preparation. Prepare the load using the following steps:
─ Disengage the Mk16 from the Mk48 prime mover according to the operator's manual.
─ Secure all hoses with tape or Type III nylon cord.
─ Tape all lights, reflectors, and glass fixtures.
─ Ensure all tool compartment doors are closed and secured.
─ Remove the safety retainer pins from the lifting eyelets located under the doors in the
bed of the trailer. Unscrew the lifting eyelets from their stored position and reinsert
the lifting eyelets so that the eyelet portion is accessible from the bed of the trailer
through the access doors. Screw the lifting eyelets all the way in and back out one full
turn. Reinsert the safety retainer pins to prevent the lifting eyelets from backing out in
flight.
Rigging. Rig the load according to the steps in Figure 3-7.
Hookup. The hookup teams stand on the bed of the trailer. The static wand person
discharges the static electricity with the static wand. The forward hookup person places apex
fitting 1 onto the forward cargo hook. The aft hookup person places apex fitting 2 onto the aft
cargo hook. The hookup team then carefully dismounts the vehicle and remains close to the
load as the helicopter removes slack from the sling legs. When successful hookup is assured,
the hookup team quickly exits the area underneath the helicopter to the designated rendezvous
point.
Derigging. Derigging is the reverse of the preparation and rigging procedures.
